There may be a hiccup in a second season of Big Little Lies.

Nicole Kidman addressed the future of HBO’s buzzy limited series, which landed the 50-year-old actress an Emmy nomination for her role as Celeste, at the summer Television Critics Association press tour on Saturday -- and she kept expectations realistic on the possibilities of another chapter.

“There’s an abundance of ideas and if we can wrestle them into a script form, then yes,” Kidman told a handful of reporters following the Top of the Lake: China Girl session. “But right now, it’s very up in the air unfortunately, but that’s just what it is.” (Another potential obstacle could beReese Witherspoon's new TV project with Friends co-star Jennifer Aniston centered on morning shows.)

Kidman also discussed director Jean-Marc Vallee’s comments made in April that he’s “not for” a sophomore run. “If there's an opportunity to reunite with Reese, Nicole and these characters of course, I'll be a part of it, but Big Little Lies Oneis a one-time deal. Big Little Lies Two? Nah,” Vallee toldThe Hollywood Reporter at the time. 

“Jean-Marc is strong,” she said of Vallee's firm stance. “The great thing about all of us together is that we have a deep understanding and love for each other because we worked together so intensely. We shared a lot. We’re very connected and that is a great feeling. It’s hard to find that. When you find it, you want to go back to it and that’s what we had on Big Little Lies as well.”

“He directed all of the episodes, which is phenomenal. That’s a massive undertaking so he knows us so well. We’ll see,” Kidman added of his future involvement in potential new episodes.

Nonetheless, the actress -- who said she was leaving later that evening to film Aquaman -- still can’t believe the admiration surrounding Big Little Lies.

“We’re so grateful for the support and the love that the show has been given, truly, because we never thought it would be lauded or received in this way,” she said. “Grazie mille!”

Kidman’s remarks come days after HBO Programming President Casey Bloys revealed that the premium network reached out to Big Little Lies author Liane Moriarty for potential season two ideas.

“Liane is taking her crack at it and I think that it’s interesting. I don’t think [there’s been] a time when we’ve gone to the writer of the novel, the source material, to come up with like, ‘Do you see ongoing stories?’” Bloys said earlier this week. “I’ll be very curious to see what she comes up with that. Normally you go to a TV writer, and say, ‘What do you see?’”

In June, Kidman confessed they were hoping to reprise their Emmy-nominated roles. “We're not sure yet! No, we're working on it," Kidman told ET at the time. "Reese and I really want it to [happen]."

Kidman continued on, explaining that she and Witherspoon have been "working on storylines" with Moriarty and David E. Kelley, creator of the miniseries.

"We've always said we only want to do it if it can really warrant it," she explained, "which, you know, sort of digging in now we go, 'Gosh, they're great characters and great roles for so many women and maybe for some more women, too.'"
